Since weather patterns tend to run in cycles of a number of years, the sequence of tree-rings in a region will also reflect the same cycling, as illustrated by the graph below.By cross-linking core samples from living and dead trees, a master sequence of annual tree-ring widths can be compiled.

They can add together to bring a shower of blessings.This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.A tree ring pattern that matches is found close to where the carbon ‘dates’ are the same. It assumes that it is approximately correct to linearly extrapolate the carbon ‘clock’ backwards. The closer one gets back to the Flood the more inaccurate the linear extrapolation of the carbon ‘clock’ would become, perhaps radically so.According to David Rohl, the Sweet Track chronology from Southwest England was ‘re-measured’ when it did not agree with the published dendrochronology from Northern Ireland (Belfast).Also, the construction of a detailed sequence from southern Germany was abandoned in deference to the Belfast chronology, even though the authors of the German study had been confident of its accuracy until the Belfast one was published.So the carbon ‘date’ is used to constrain just which match is acceptable.

Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system.

) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.

This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology.

The earliest evidence of writing anywhere in the world only goes back about 5000 years.

Paleoanthropologists frequently need chronometric dating systems that can date things that are many thousands or even millions of years older.

Fortunately, there are other methods available to researchers.
